[movies]AIM Spacecraft Deployment - NASA/Goddard Space Flight Center Conceptual Image Lab
The Aeronomy of Ice in the Mesosphere (AIM) mission will provide the first detailed exploration of the Earth's unique and elusive noctilucent or night shining clouds that are found literally on the 'edge of space'. Located near the top of the Earth's mesosphere (the region just above the stratosphere), very little is known about how these polar mesospheric clouds form or why they vary. They are being seen at lower latitudes than ever before and have been growing brighter and more frequent, leadi...

[movies]AIM's Cosmic Dust Experiment and Cloud Formation - NASA/Goddard Space Flight Center Conceptual Image Lab
Like clouds in other parts of the atmosphere, one element required for polar mesospheric clouds to form is tiny dust particles on which water vapor can accumulate and grow into ice crystals. Nearer to Earth's surface, clouds form from 'cloud condensation nuclei' that can be sea salt spray, desert dust, or other materials lofted from the surface. In the mesosphere it is thought that cosmic dust particles falling into the Earth's atmosphere might serve this same purpose, and the Cosmic Dust Experi...
